The posited deal merging H3G and O2 would create a new largest UK mobile operator with 40% market share, with massive synergy benefits available from cutting overlapping network and operations costs

Regulatory hurdles would be very significant, and the remedies required may well counteract the benefits of reduced network operator competition, as they will be designed to do

For Vodafone and EE, the impact will be mixed; a potentially aggressive competitor is removed, but their preferred positioning as being the best mobile networks is under threat

This note discusses the likely obstacles to a successful launch of H3G UK, the most aggressive 3G new entrant in Europe. Our main points:

What does this mean for the media industry? Does the increasing power of media buyers mean further downward pressure on rate cards? We suspect that many of the effects have already been felt, particularly in the European and US TV businesses. In fact, we see a different issue emerging: the explosion in advertising inventory in the last few years, which has resulted in a worldwide glut. This has coincided with what we think may be a permanent reduction in the absolute number of advertisers. As a result, media buyers will continue to obtain better terms, whether in buying as part of a large group or not, but media price deflation may be a feature of the industry for many years to come.
